IMPROVEMENT IN MACHINES FOR WASHING PAPER STOCK.

Specification forming part of Letters Patent No. 137,696, dated April 8,1873 application filed October 2, 1872.

To all whom it may concern:

Be it known that I, GEORGE LANGDON LOVETT, of Fitchburg, in the countyof Worcester and State of Massachusetts, have invented certainImprovements in Machines for Washing Paper Stock, of which the followingdescription, taken in connection with the accompanying plate of drawinghereinafter referred to, forms a full and exact specification, whereinare set forth the nature and principles of the invention, by which thesame may be distinguished from others of a similar class, together withsuch parts thereof as are claimed as new and are desired to be securedby Letters Patent of the United States.

The nature of my invention relates to an improvement in machines forwashing paper stock; and consists in a stationary cylinder, having oneor both ends open for the discharge of water, and an opening in itsside, into which the buckets of the revolving washor or cylinder emptyas it revolves around it,

as will be more fully set forth hereafter.

Figure 1 is a side elevation of my invention. Fig. 2 is a cross-sectionof the same.

A represents a stationary cylinder, having one or both of its ends open,and an opening, a, made through its top. Revolving around this cylinderis the rotary washer 0, having grated sides R, covered with wire orother suitable screens, and having a number of buckets, B b b, whichrevolve with the washer as it turns upon the cylinder A. At each end ofthe washer is placed a suitable packingbox, G, so as to prevent leakage.

As the washer revolves through the paper stock, and the dirty waterpasses through the screens on the sides, it is caught up by the bucketsB and carried around until it reaches the opening a, when itis at oncedischarged into the cylinder and flows away.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- 1 The cylinder A, having the opening a, incombination with the revolving washer 0 providedwith the buckets B,substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this27th day of July, 1872.

GEORGE LANGDON LOVETT.
